F. PASCHKE El' AL DEVICE FOR THE TREATMENT OF' ARTIFICIAL SILK FiledJan. 2, 1931 2 Sheets-Sheet 2 fave/220m:

in its essential parts of the distributing boX m for the liquid, havingsuitably attached pipe sockets n positioned at the same distances fromeach other as the holes in the .vashing frame. The said frames areplaced onto these sockets and pressed down tightly by means of a knucklelever 0 or the like.

The device according to the invention is preferably used not only forthe washing of the threads but also for other wet treatments, especiallyfor desulphurizing. In such cases the frames may remain in the washingdevice in which only the liquid is changed, or they may be removed andtransferred to another device of a similar kind. After treatment thebobbins are dried in the same frames on which they had passed throughtheir wet treatment.

As will be gathered from the foregoing de scription, the essentialfeature of the new process according,r to the invention consists in thatthe bobbins are placed in the washing frames directly at the spinningmachines in which they pass through the whole yfurther process until thesilk is completely dried and finished. Thus, from the spinning machinesto the end of the process no more handling of single bobbins isnecessary, but only of complete frames containing a large number ofbobbins, whereby a time-saving and very convenient way of handling isprovided. The best result-'gs of this new process can be observed withsilk of the more sensitive kinds of which the output and quality havebeen y considerably improved.

The dried silk is preferably wound straightaway onto suitable bobbins orbut it may, of course, also be reeled into the form of hanks as desired.

What we claim is:

l. In a device for treating artificial silk, a washing device comprisinga distributing box for the liquid, a frame comprising a loose and afixed side member situated opposite to each i other, bars between saidside members for the reception of the bobbins and of interposed packingrings, means to lock said loose members in a raised position, holesformed in said fixed side members for the reception of said bars, thetreating liquid passing 'lirough said holes on its Way to the bobbins,and pipe sockets on the distributing box in contact with said holes.

2. In a device for treating artificial silk, a portable frame forcarrying silk bobbins, comprising in combination, a carrying member, aloose member situated opposite he first-mentioned member, means forconnecting said members, a plurality of bars adaped to receive said silkbobbins and cr -ed by said members, packing rings on said bars, holesformed in the first-mentioned member and adapted to receive an end ofeach of said bars, a space being left letween the walls of said holesand said bars for The p of the treating liquid, cavities formed in thesecond-mentioned member and adapted to receive the other end of each. ofsaid bas connec'fed with said means and second-mentioned member, mlocking the second-mentioned ircn'iber.

3. In a device for treat' ,1g rtl al silk, a washing device comprising adistrilnning box for the liquid, a frame com'n'i a loose and fixed sidemember situated opposite each other, means for moving said loose member,means for maintaining said loose member in position, depressions f-,rmedin the loose member, holes formen in vthe fixed member, bars ofcross-shaped section placed between said loose and ixed memE 5:, theends of said bars being reduced for insertion in said depressions andholes, and pipe sockets on said distributing box in contact with saidholes.

In testimony whereof we aiiix our signa` tures.
